Abstract : An operator's performance in a target acquisition task may be influenced by variables which are not directly associated with the target and imagery but are associated with the decision rule employed by the operator. The separation of factors that influence the operator's decision criterion from those that influence sensitivity is a major contribution of the psychophysical application of the Theory of Signal Detection (TSD). This report focuses on practical application of TSD to the problem of operator acquisition of targets in sensor imagery which ray, or may not, have been prescreened by an automatic target recognizer. The foundation of TSD in Statistical Decision Theory is discussed as well as specific methods for applying TSD to laboratory evaluation of the target acquisition task. A brief review is presented of target acquisition studies in which TSD was utilized.
